EVELYN P. SPERRYIOF OAK PARK, ILLINOIS. MECHANISM FOR OPERATING AND SECURING WINDOWS Specification of Letters Patent.

Application filed August 12,1906. Serial No. 273,880.

To all whom it may concern.-

Be it known that I, EVELYN P. SPERRY, a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in-Mechanisms for Operating and Securing Windows, of which the following is a specification.

, My invention relates to that class of mechanisms for operating and securing windows having an operating-lever provided with means for securing it to a suitable support, such as a window-frame, means for flexibly securing it to the window to be operated, and means for securing the operating-lever in different adjusted positions.

j The principal object of my invention is to provide a simple, economical, and efficient mechanism for operating and securing win (lows.

. Further objects of the invention are to provide means for operating the Window from the inside to diflerent adjusted positions and means for rigidly holding the window locked in any desired open position to which it may be adjusted and for holding it locked in closed position, such operating and locking mechanism being adapted to be operated from the inside and inaccessible from the outside.

Other and further objects of the invention will appear from an' examination of the drawings and the following description and claims.

The invention consists principally in anapparatus having an operating-lever provided with means for pivotally securing it to a suit-' able support, such as the window stool or sill, means for flexibly securing such operating-lever to the window to be operated and means for. locking ,theoperating-lever, and thereby the window, in difierent adjusted positions.

It consists, further, in providingsuch op erating and locking lever mechanism with a supplementary connectingdevice for holding the window securely locked in closed position independently of the operatin lever mechand securing mechanism, showing it connected with the window and inlocked position, the window being closed; Fig. 2, a plan View showing the window partially open and the operating mechanism in a corresponding position and unlocked; Fig. 3, a view in elevation, showing the operating mechanism in closed position; and Fig. 4, a transverse sectional elevation taken on line 4. of Fig. 1 looking in the direction of the arrow.

In constructing a window provided with casement-windoWadapted to be swung in a horizontal plane to open and closed positions.

For operatin and locking the window from the inside an holding it in different adjusted positions and locked in such manner that the locking mechanism is inaccessible from the outside I provide a main operating-lever d, which is secured to the sill c of the window beneath the inside window-sill.

In order to provide suitable means for pivotally securing the operatin lever to the window-sill, the lever is provi ed with a perforation adapted to receive a pivot-pin e in the'form of a rivet or screw by meansof which such lever is pivotally secured to a metallic base-plate f, which base-plate is in turn secured to the window-sill or lower inner portion of the window-frame formed by the window-sill and apron by means of screws g.

This operating-lever is operatively connected with the Windowsash by means of a connecting link or lever h, which is pivotally connected with the outer swinging end of the operating-lever by means of a rivet 'i, and a rear end portion of the connecting-lever his pivotally connected with a link 7c by means of a rivet Z, the link being pivotally connected with the base-plate by means of a rivet m. The end of the lever h adjacent to the window is flexibly connected with the window-sash by means of sliding operating-rod n, wh ch is slidably mounted in a bracket 0, hav ng perforated lugs 1), through which such slldlng rod extends. This rod is flexibly connected with the adjacent end of the lever 72. by means of a metallic lug portion g, which may be ntegral with the rod, and by a rivet r,wh1ch forms a pivotal connection between the lever h and the sliding rod. The sliding rod or bar 7 is of suflicient length to extend over the screws or bolts 8, which secure the brackets the opposite side of such to the window-sash. These screws are thus constantly covered by the rod 01 bar and are inaccessible when the window is open.

The main operating-lever is provided: with a serrated or toothed segment 75, the'toothed end of which extends in the arc of a circle and the center of which forms the pivotal center of the operating-lever. A toothed pawl a is pivotally-mounted adjacent to such toothed segment upon pivot 12, which is -provided with a hook portion 111, adapted to engage the end of the lever h and extends partly around the rivet 1 when the window is closed, thus forming, in connection with the lug g, slidable bar a, and brackets 0, a direct connection with the window-sash independently of the operating-lever mechanism.

A locking-lever y is pivotally mounted upon the baselate upon pivot-pin 2 adjacent to the swinging end of the securing-pawl and on awli from its toothed edge. The end portion 2' of this locking-lever which is adjacent to the securing-pawl is in slidi engagement with a convexed or curved si e 3 of the securing-pawl and is adapted to be moved to the posltion' shown in Fig. 1 to engage such securing pawl at a (point substantially at right angles to a line rawn from the pivot z to the pivot v of the pawl. When in this position, It be readily seen that the locking-lever securely holds the pawl locked in engagement with the toothed segment portion of" the operatinglever.

To release the operatin -lever, and theneby the window, the lockin ever y is. moved to,

the position shown in i .2; in moving-to this position its inner en engagesthe ing 4' of the securing pawland becomes disengaged from the curved surface portionthereof', so that the pawl is moved out of enga ement with the toothed segment and the hoo w out of engagement with the lever h and the win.- dow thus released. By this arrangement it will be readily seen that the inside windowstool may be mounted over the window operatin and locking mechanism above describe and that the window-screen 5 may extend between the locking-lever. mechanism and the inner end of the o crating-lever and the window. It will also e noted that the connecting-levers h and k are pivotally connected, respectively, with the windowsash and window-sill, the connection with the window-sill bein intermediate the opposite ends of the lever when the windowis closed.

The main operating-lever is also pivotally con-- nected with the lever h in such a manner as to increase the movement of the window with relation to the movement of the main operatwindow and window-sill when theformer is in 0 en position, as shown in Fig. 2.

T e main 0 crating-lever is provided at its inner end wit an operating-handle 6, Which may be of any ordinary and well-known form, and a. locking-lever is provided with a handle 7, also of any ordinary and wellknown form. I prefer, however, that these handles should extend downward inside of and beneath the window-stool, so as to be inaccessible from without and readily operated from within.

By the above arrangement it will be seen that a window (gperating and locking mechanism is provid ada ted too erate a casement-window and to securely och it in desired adjusted position, either open or ciosed, that the means for securing-the operating-lebe covered so as to be inaccessible when the window is open, and that the locking and operating mechanism is inaccessible for the purposes of operating the window or hockingor unlocking it from without.
